What is an EdCamp? According to edutopia, Edcamps are: Free to all participants; A free-flow of ideas and information about education, education technology and best practices for teachers; An unconference model of sessions throughout the day for spontaneous topics, chats and activities; The ability of being a presenter is at your discretion (and courage)
Tanning bed bulbs and lamps should be replaced when they have been used to 80 percent of their expected life cycle, and typically hit this mark about one year after they have been installed. Low-pressure lamps have a life cycle of 300 to 1,700 hours, while high-pressure bulbs last 300 to 9,500 hours.
Although most lamps are rated for 1000 hours of life, we recommend changing them at between 600 and 700 hours to guarantee optimum tanning performance. For best results, always change all of the lamps at the same time. This will reduce the likelihood of some lamps being weaker than others are.
